IoT Security is Hard: Here’s What You Need to Know
Security for anything you connect to the internet is important. Think of these devices as doorways. They either allow access to services or provides services for someone else. Doorways need to be secure — you wouldn’t leave your door unlocked if you lived in the bad part of a busy city, would you? Every internet connection is the bad part of a busy city. The thing is, building hardware that is connected to the internet is the new hotness these days. So let’s walk through the basics you need to know to start thinking security with your projects.

New Part Day: Very Cheap LIDAR
Self-driving cars are, apparently, the next big thing. This thought is predicated on advancements in machine vision and cheaper, better sensors. For the machine vision part of the equation, Nvidia, Intel, and Google are putting out some interesting bits of hardware. The sensors, though? We’re going to need LIDAR, better distance sensors, more capable CAN bus dongles, and the equipment to tie it all together.
This is the cheapest LIDAR we’ve ever seen. The RPLIDAR is a new product from Seeed Studios, and it’s an affordable LIDAR for everyone. $400 USD gets you one module, and bizarrely $358 USD gets …read more
Automate the Freight: Drones Across the Sea
When you think about which of the many technological advances of the 20th century had the most impact on the global economy, which one would you rank as the most important? Would it be the space program, which gave rise to advances in everything from communications satellites to advanced composite materials? Or would it be the related aerospace industry, which stitched the world together so tightly that you can be almost anywhere on the planet within 24 hours? Or perhaps it’s the Internet, the global platform for buying almost anything from almost anyone.
Those are all important, but for the …read more
E-ink Display Driven DIY
E-ink displays are awesome. Humans spent centuries reading non-backlit devices, and frankly it’s a lot easier on the eyes. But have you looked into driving one of these critters yourself? It’s a nightmare. So chapeau! to [Julien] for his FPGA-based implementation that not only uses our favorite open-source FPGA toolchain, and serves as an open reference implementation for anyone else who’s interested.
Getting just black and white on an E-ink display is relatively easy — just hit the ink pixels with the same signal over and over until they give up. Greyscale is made by applying much more nuanced voltages …read more
You Think You Can’t Be Phished?
Well, think again. At least if you are using Chrome or Firefox. Don’t believe us? Well, check out Apple new website then, at https://www.apple.com . Notice anything? If you are not using an affected browser you are just seeing a strange URL after opening the webpage, otherwise it’s pretty legit. This is a page to demonstrate a type of Unicode vulnerability in how the browser interprets and show the URL to the user. Notice the valid HTTPS. Of course the domain is not from Apple, it is actually the domain: “https://www.xn--80ak6aa92e.com/“. If you open the page, you can …read more
